We lifted part of this patio slab so that rain water is graded away from the foundation of the home. In the far part of the patio in the pictures, (near the home) we injected our PolyLevel foam under the slab to slop the patio away from the home. We then sealed all the cracks and gaps with our NexusPro sealant, which is UV resistant. The sealant will help keep water away from the foundation of the home and inbetween the cracks.
